MULTIPLE- RECORD PHONOGBAIPH.

Application med January as, 192:. Serial no. 815,682.

My invention relates to im rovements in phonographs and it consists theconstructions, combinations and mode of operation herein described andclaimed. An object of the invention is to rovide a phonograph which iscapable o playlng more than one record in succession, repeat thesuccessive playing as many times as may be desired and perform all ofthe'funct ons m necessary to changing the records,.plac 1ng the tone armand reproducer in position, -starting the turntable, etc.,automatically.

Another object of the invention is to provide a phonograph of theforegoing description which has only two visible control means, namely,one, an electric starting and stop ing switch, the other, a lever whichis movab ie toregulate the playing from 10" to 12"records.

the .action pf thc rnain and counter shaft gears in-perforiningthorecord changing Byway of introduction, the' attention of the reader isdirected to Fig. 1 which shows selves are omitted from the illustration,but

the reader can readily imagine them in place.

Disposed at the-right of the carrier stack is the turntable of thephonograph. It is the t'unction of one ofthe carriers to go through thefollowing cycle of operations: The carrier" swings around over theturntable; the turntable is raised to life the record oil of the carrierand simtiltaneously with this operation, contact of the record is madewith the needle, and the turntable starts to revolve and continuesrevolving. until the playing of the record is finished; the turntablelowers so as to replace the record on the carrier, the carrier is swungback into the stack, and the entire stackis then raised sutlicientlyhigh to permit the next lowest carrier to.swing but over the turntable.

The foregoing cycle 01" operations is repeated in respect to eachcarrier until the entire stack of records is played, whereupon theentire stack lowers to the original posi tion and all of the cycles ofoperation are repeated unless the operator opens the main electricswitch. In such event,'the phonograph will stop playing after theplaying of the record then in position is finished. The reader canhardly appreciate the significance of the acts enumerated above in advance of understanding the following (lescription, and therefore,attention is now directed to the general construction which is followedby a description of the details of construction and' that in turn isfollowed by a description of the operation. The records to be played arefitted into carriers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12. One ofthese is shown in detail in Fig. 18. The

carriers, and naturally the records, which are intended to be carriedthereby, are normally arranged in a stack at the left of the turntable13. The turntable shaft 14 is capableof raising and lowering and in sodoing, takes the turntable with it. The turntable must be in the loweredposition (Fig. 26) in order to permit the carrier 2 (used as an exampleof one of the carriers) to swing a record into position over theturntable.

is swinging of the carrier '2 is accomplished by a yolk 15 (Figs. 2, 3,4, l4 and 16). The yoke has a lug 16. The respective carriers 1, 2, etc.are mounted on holders is in the lowered position.

eanna 17, 1s; 19, 2o, 21, 22, 23, 24, 25, 26, 2? and 28"(Fig. 3). Eachof these holders has abutinents 29 (Figs. 2-and 17) which are spacedapart to provide a recess 30 with which the lug" 16 enters in lookingengageyoke 15. A link 32 (Fig. 4) connects the crank to the swinginglever 33. This level has a pin 3 1 (which may include a roller)occupying acam groove 35 in the cam drum 36. The drum is fixed upon acountershaft 37 and when thisshaft is made to revolve, so as to turn thecam groove 35 from the position in Fig. 7', to the position in Fig. 1,the yoke 15 is moved through one-quarter ofa circle from the full lineposition in Fig. 7 to the full line position in Fig. 4 and the carrier 2is transported from the stack to the positionover the turntable 13, asstated before. .1 I

All this happens while the turntable 13 lit is necessary to start thestylus 38 of the reproducer 39 (Figs. 1 and 2) at the beginning of therecord. The stylus stops near the center of a record at the end of aplaying operation, and it is necessary to get it back to the edge beforethe playing of the second'record' can be begun. For this purpose, eachotthc carriers 1, 2, etc., has a flange 40 at the edge nearest to theturntable. The tone arm 11 carries a'finger43.

IUD

As the carrier 2 sweeps across to the posi-.

tion over the turntable 13 where the record is intended to be, theflange 40 engages the finger 13 and moves the .tone arm over into theposition in Figs. 1 and 2., There is nothing to obstruct the passage ofthe tone arm and its carried parts to this position because the readermustremember that the turntable is still in the lowered position and thecarrier operates in a plane too far down to interfere (compare Figs. 19and 20). It is also necessary to note that when the turntable 13 islowered, the record is entirely out of range of the stylus 38 (examinethe dotted and full line positions in Fig. 19), and it is not until theturntable is raised that the stylus engages the record in readiness toplay.

The next act is to raise the turntable 13. This is done by the raisinglever 44 (Figs. 11 and 26). This lever is carried by a shaft 45 which,at the other end, has an arm 16 with a roller 47 in engagement with thecam 48 which oscillates the arm. When this cam is in the position inFig. 26, the turntable 13 is lowered. When it is in the position inFigs. 6 and 11, the turntable is raised.

he reciprocating cam 48 (so called be cause of its function)isfi'xed-upon the main shaft 49 which actua 1y consists of two parts,the other part beingdesi nated 50 in Fig.

.9. There is-a reason for the distinction; the part 49 is driven. onlyintermittently, while the part 50 is driven continuously while thephonograph is in operation. v

For this purpose, the shaft 50 carries a which a driving worm gear 52meshes. This gear is revolved by a driven worm gear a 53, which in turnis driven by a worm pinion 54 on the shaft 55 of'the 'motor 56. Carriedwith the master gear 41, by virtue of being mounted on the saine shaft50, are timing drive gears 57, and 58' Eachdrive gear has a pair ofteeth 59 and 60' respectively', the teeth of each pair being'disposeddiametrically opposite each other, as'plainly shown in Figs. 8 and 11.

7 That portion of the shaft 50 upon which' the timin drive gears aremounted, is made non-circa air as at 61 (Fig. 9). The purpose of thisarrangement is to permit sliding the gears on the shaft but atthe sametime co'm-' pel them to turnwith the shaft. The gears are made in onepiece, there being a connecting collar 62 provi'ded with an annulargroove 63 which is occupied by the shifting yoke 64. This yoke hasconnections 65 and 66 (Fig. 3) to a lever 67 by means of which thetiming gears may either be slid into the position In Fig. 9, or into theopposite position on the shaft, the respective posi tions representingthe setting of the mechanism for playing 10 and 12" records.

When the timing drive gears areshifted back to the position in Fig. 9,the teeth 59 are in registration with the tooth recesses 68 of a starWheel 69. This star Wheel is loose on a shaft 70, and this shaft carriesa second star wheel 71 which is precisely like the wheel 69 exceptingthat it has eleven tooth recesses 72 instead of nine tooth recesses asin the wheel 69. The timing drive gears being shifted, as stated, bringthe gear 58 to a position where the teeth 60 are out of registrationwith the star wheel 71 (Fig. 3) and therefore, according to thesituation under description, it is only the teeth 59 which are effectivein turning the wheel 69,

the other star wheel 71 remaining idle.

Continuous 'rotation of the gear 57 pro-' duces an intermittent movementof the star wheel 69 by virtue of the periodic engagement of the teeth59 with the recesses 68 (Fig. 10). There is'a'pin 73 on the wheel .69,and a corresponding pin 74 (Fig. 3) on the wheel 71, and as the formerultimately engages the heel 75 of the clutch lever 76, a

' tillnlfilg movement of the clutch lever and upper end of this lever 76then presses in its s pporting shaft 77 is produced. The

ment with one or the other of a. pair of ing cam. 48 from the .raisingof the turntable 13. master gear 51 (Figs. 9,10 and 11) with clutch lugs79 on the master gear 51 is made. The aforesaid continuous movement ofthe master gear is now imparted to the main shaft part 49 so-as torevolve the reciprocat- 1position in Fig. 26 to that'in Figs. 6 and 1 tocause the rocking of 'the raisinglever 44 and the consequent" A i: theturntable nears thelimit of the raising movement, contact of the record.with

the stylus 38 is made. The turntable 13 lever 44. The clutch lever 7 6disengages the' dog 78'by virtue of its tendency to .gravitate to theright (Figs. 11 and 12) as soon as the pin 73 passes the heel 75. Theextension main shaft 49 comes to a standstill after having made onecomplete revolution. The disengagement of the clutch dog 78 is caused bya spring 81 pressing outward on a plug 82 and in turn against the clutchdog when the dog reaches a'lateral passage which it is adapted tonormally occupy. It is then that the shaft '49 stops after the aforesaidcomplete revolution.

. As the playing of the record continues,

successive engagements of the recesses 68 of the star wheel 69 by theteeth 59 of the gear 57 move the pin 73 aroundinto' another 'en--gagcmeiit' with the. heel 75 (Fig. 10). Theclutch lever 76-thereuponagain moves the.

clutch dog 7 8 (Fig. 5) into the path of the lugs 79 on the master gear71, and the ex-,

tension main shaft 49 makes another revolution as before. -Thereciprocating cam 48 departs fro-m the arm 46' (Fig. 6) and theturntable lowers to' the' original position in Fig. 26.

With this lowering act, the played record is re-deposited upon thecarrier 2. The st lus'38 remains suspended near the center 0' theturntable where the playing stops.

As soon as the turntable'has been lowered, the carricr'2 is swungback'intoft-he original position in the carrier stock, and when thecarrier has assumed its proper place, the entire stack is raisedsufliciently far to bring the carrier 3 into the position formerly-econpied by the carrier 2. -This.is accomplished in-this way The extensionmain shaft 49 carries a drive gear 83 (Fig. 6) which of course befrom aposition in Fig. 6. The first of rotational movement of the shaft 37 isoccupied in swinging the carrier 2 from the position in Fig. 4.- to thatin Fig. 7. The next 90 of movement is occupied by the lifting dog 87 inraising the rack 88 the distance between a pair of the teeth 80 as thereader the raising of the rack must raise the carrier stack. The nexthalf revolution of the shaft- 37 is occupied in shifting the swinginglever 33 back to the position in Fig. 4-, and this time it is thecarrier 3 which swings over the turntable with the next record to beplayed. Attention is next directed to the detailed construction whichintroduces ele ments which must necessarilybe described so as to makethe understanding of the invention clear. The foregoing mechanism iscarried by a phonograph cabinet 90. There is a depression 91 on one sidefor the accommodation of the carrier stack and a closed compartmentf92on the other side for the housing of the operating mechanism, assuggested by Fig. 3. Each carrier is made exactly like the next. Thecarrier may be pressed out of sheet metal to form a vertical wall 93 andan inturned flange 94 to receive and support a record. The supportingpart of the carrier is circular, and is sufficiently larger than asemi-circle to prevent the rec 0rd slipping out edgewise at the openfront.

At the back, the carrier hasa pair of lugs 95 and an opening 96. Thelugs 95 are adapted to enter the corresponding openings 97 (Figs. 3 and17) in the vertical Wall 98 of the holder 18, and the opening 96 isadapted to receive the lug 99 on the front of the shelf 100. Thatpart'of the holder that has the wall 98 and shelf 100 extends out at oneside of the otherwise circular holder (see Figs. 2, 4 and 17) so as tomake it very easy to fix the carriers in place. The carriers ordinarilyare intended to remain in place when once applied unless it be desiredto change the phonograph for playing 12 records. In this event, largercarriers are employed but as these are in all respects (except in size)the same as the car riers already described, additional illustra tion isdoubtless unnecessary.

The sides 101 (Fig. 17) engage the inturned edges 102 of the hood 103(Figs. 2 and 4) and the holders are thereby guided in the up and downmovement of the carrier stack. It is not until one of the holders andcarriers (18 and 2, for example) reach the slot 104 in the hood 103 thatthe carrier and holder may be swung out toward the turntable 13. I

. operations.

123 presses the measure plate of the series rests on a support 109.

The collar of each plate engages the plate next succeeding and a cover-binds them all firmly together. This cover is screwed into place on theupper end of the sleeve 106 and is locked in position by a jamb nut 111.

The individual holders rotate upon the collars 108, and felt or othersuitable friction washers 112 are fitted in the spaces adjacent to theholders and plates 107. The hollow shaft 105 is fixed at the top of thehood 103 by the plug 113 and nut 114. The plug includes a smooth portionupon which the yoke 15 revolves. arrangement at-the bottom. A. plug 115both fixes the lower end of the shaft 105 and provides a bottom bearingfor the yoke.

A dash pot 116 depends from the plate 117 in which the bottom plug 115is fastened. A piston 118 operates in the dash pot. The passage of airinto and out of the dash pot is controlled by a valve 119 which may beadjusted to vary the size of the orifice. Connection is made between thepiston 118 and rack 88 so that the two move together. The action of thedash pot retards the gravitation of the carrier stack when the lastrecord is played and the mechanism is about to readjust itself torepeatta cycle of playing The rack is afiixed to the bottom support 109as shown in Fig. 3.

A hearing plate 120, at one side of the rack 88 (Figs. 3 and 15),provides a support for one end of the countershaft 37, a

pawl 121 and latch 122. The pawl 121 furnishes a back check for the rack88 and supports it in position after the lifting dog 87 departs fromengagement with one of the teeth 89 after having lifted the rack and thecarrier stack as described above. A spring pawl into the engagingposition. I

The pawl 121 has a heel 124 which is adapted to be lifted intoengagement by the latch 122 by a pin 125 on one sideof the rack afterthe last record has been played and the lifting dog 87 performs itsfunction for the last time in respect to the stack of records then inthe process of carrying out a cycle of operation. Upon occurrence ofthis event the pin 125 raises the heel 1241 into engagement with thelatch 122 and the pawl 121 out of engagement with the teeth of the rack.The lifting dog 87, in completing its revolution, departs from the rackand so leaves the latter unsupported.

Thereupon the rack and the stack of records and carriers gravitatetoward the origmal posltion, and as soon as the stud 126 There is asimilar its (near the top of the rack) reaches the heel 127 of the latch122, the latch is rocked from engagement with the heel 124 of the pawl,.

and the pawl re-engages the rack as shown -in Fig. 14. The engagement atthat time will be with the rack tooth 89 next highest up, therebyrepresenting the first .holder 17 and carrier 1 to be in position toswing out of the slot 104 and over the turntable 13.

Mention of the edges 102 of the hood 103 being turned in to form guides,has been made. These guides occur at the sides of a vertical openingthrough which the supporting shelves 100 of the holders on the inside ofthe hood extend. As the holders move well below the hood 103 (Fig. 3) toreach the original or starting position, it is necessarythat the guides102. also extend at least as far as the lower extremity of the holder ofthe wires and in parallel in respect to each other, are the mainelectric switch 132 and the automatic electric switch 129. As long asthe main switch 132 remains closed, the opening of the automatic switch129 will not interrupt the flow of current to the driving motor, butshould the switch 132 be graphwill stop.

opened, a succeeding opening of the automatic switch 129 (which openingoccurs periodically) will interrupt the flow of current so that thedriving motor must stop.

This is what actually happens when the operator desires to stop thephonograph. He may desire to stop the phonograph while a record is stillbeing played. The playing will continue until the end of the record isreached, and when the mechanism operates to swin that record back intothe stack (Fig. 7), w ich act represents 180 of angular motion of theshaft 37 from the position in Fig. 4, the switch cam'128 will assume acorresponding relative position, in other words, the dotted lineposition rather than the full line position in 'Fig. 25. Both electricswitches will then be open and the phono- The automatic'electric switchcomprises a pair of terminals 133 between which the con.-

.tactor 134 is adapted to move to complete the current path. Thiscontactor is carried by an armature 135 which is urged upwardly by aspring 136 but is pressed downwardly by the engagement of the cam 128with a button 137 extending up from the armature.

Bearings 138, 139, 140 and 141 (Figs. 3 and 9) furnlsh the supports forthe various shafts involved. The bearing 138 furnishes the support forone end of the countershaft 37 and also for one end of the extensionmain shaft 49. At one side of the bearing 138,

there is an enlargement 142 (Fig. 3) b which the idler 85 (Fig. 6) issuppo'rte Carried by the extension shaft 49 outside of the bearing 139is a coupling head 143 which carries the dog 78 (Fig. 5) forming part ofthe auxiliary clutch referred to in the first part of the descriptionabove. This clutch IS an auxiliary to the main clutch 80 (Fig. 11) thelatter controlling-the turning of the turntable, the former the swingingof the record carriers, the elevation and depression of the stack andthe operation of the automatic electric switch. One side of the couphng143 is cut out at 144 to make room for the dog 78 which is movablymounted at 145 on the coupling. Both the sprin' 81 and plug 82, whichact to press the 0g outwardly, are fitted in a bore 146 in the largepart of thecoupling. i

The free end of the clutch do normally occupies the lateral passage 146o a circular opening 147 of a standard 148, in which circular openingthe clutch lugs 79 of the master gear 51 rotate. As long as the dogoccupies the lateral passage, the clutch lugs have no engagement withthe dog, but as soon as the clutch lever 76 presses the doginwardly,such engagement is established and the extension main shaft 49 causedto-rotate with the main shaft 50.

The worm 52 (Fig. 11) which drives the master gear 51, is supported by acircular casing 149 and a plurality of screws 150,

these respective parts acting as spacers betweenthe worms 52 and 53. Thecasing also houses the friction clutch which, as stated above, does notoperate to drive the turntable shaft 14 until the friction disks ofwhich it is composed, are pressed together by the raising lever 44. I

A supporting plate 151 is one of the elements of the frictionlclutch.This plate rests on the shoulder provided by the bearing plug 152 inwhich the lowermost end of the shaft 14 is fixed. A spring late 153(Fig. 13) rests on the supporting'p ate, and.

it isthrough this spring plate that the proper 50 and its carried parts.The turntable shaft 14, on the other hand, rotates only while a recordis'being played. A. portion ot"the bearing plu 152 occupies the bearingcup 157 b whic the bearingball 154 is containe This cup has 1 straversed by a pm 158 with which the b ihurcated end of the lever 44hasengagement.

Reference is again made to the timing drive gears 57 and 58. These arecast en bloc as shown in Fig. 9. When the lever 67 (Figs. 1, 2 and 3) isshifted to the left, the timing ear 57 occupies a position 1nregistration with the star wheel 69. The phono aphis now adjusted toplay 10 records. l he turntable 13 rotates at 80 R. P. M. for three andone-half minutes it a 10 record is to be played, and in that time, themaster gear 51-and the driving gear 57 will have made a suficient numberof revolutions to have advanced the pin 73 (Fig. 10) into engagementwith the heel 7 of the clutch ill) lever 76. The reader will rememberthat the star wheel 69 is moved intermittently by the periodicengagements of the teeth 59 with the tooth recesses 68 in the star wheel69., this number being in proper proportion to the three and one-halfminutes playing period of a 10 record. Should the phonograph be set forplaying 12 records, the

lever 67 should be shifted toward the rightso that the timer drivinggear 58 is brought tit) into registration with the star wheel 71. Thedrawings do not show the gear- 58 in such driving engagement, but thereader can readily understand how this is accomplished by examiningFigs. 3 and 4. The periodic engagements of the teeth of the gear 58 thenbecome efiective in moving the star wheel 71. This wheel has eleventooth recesses corresponding to the longer playing period of the 12record.

It requires approximately four and onehalf minutes to play such arecord, and in this time, the star wheel 71 will have made onerevolution and the pin 74 will have been advanced far enough to engagethe heel of the clutch lever 76. When this gear is engaged and theclutch lever 76 is rocked, the clutch dog 78 (Fig. 5) is thrown intoengagement with the clutch lugs 79 so that the extension main shaft 49begins to revolve ,with the main shaft 50. This causes the turntable 13to be lowered, the carrier 2 with the played record; to swing back intothe stack, the elevation of the stack so that carrier 3 occupies theposition formerly occupied by carrier 2 and causes the carrier 3 to beswung out over the turntable.

The tonearm 42 is made in two parts, namely, the part 42, describedbefore, and a part 159 which is hingedat 160 on the part 42 so as to becapable of slight upward movement with the record when the turntable 13is raised as in. Fig. '19. A bracket 161 is-tt swinging as the carriersweeps away over the turntable.-

'A spring 164 presses down on a lug at the rear end of the finger so asnot only to hes the linger in engagement with the movab e part 1590f thetone arm, but also to follow that part through the slot 162 when it lsrocked on its hinges 160. when the turntable is raised. The purpose ofthis provision is to insure getting the finger 43 out of the way of therecord and of the turntable, and Fig. 19 shows how the finger clears therecord.

The operation is now reviewed so as to describe the occurrences in acycle of operation in the sequence by which they happen. Assume thecarrier 2 to be in the position around the turntable 13 (Figs. -1 and2), the turntable 13 to be raised and rotating (Fig. 19) and the stylus38 as approaching the center as the playing of the record progresses.

The reciprocating cam 48 stands in the position shown in'l igs. 6, 27and 11. The extension main shaft 49 by which it is carried, isstationary. The cam 48 holds the turntable up (see Fig. 11). The mastergear 51, is, however, rotating in the counterclockwise direction, as itdoes continuously as long as the phonograph is playing. By repeatedengagements of the timing gear teeth 59 of the gear 57 with the recesses68 of the star wheel 69 (Fig. 10), the pin 73 will ultimately reach theheel 75 and shift the clutch lever 76 in, so as to move the clutch dog 78 into engagement with the nearest or the lugs 79 on the revolvingmaster gear 51.

This establishes a connection between the master gear and the extensionshaft 49 so that the latter too begins to rotate. Mention must be madeof the fact that approximatcly three-fourths of a revolution of theshaft 49 equals a full revolution of the 2/4, 3/4 and 4/4. Consider Fig.4. The

swinging lever 33 is inclined toward the right, having-been moved tothat position by the depression in the cam groove 35, and consequentlthe carrier .2 occupies the position amun the turntable, as statedbefore.

Imagine the rotation of the shaft 49 as having begun. The reader willremember that the dog 78 was moved 1n. As soon as the cam 48 departsfrom beneath the roller 47 (E i 11) the turntable 13 must lower. The s at 49 makes almost a quarterrevolution before the zero 'mark on the gear83 reaches the idler 85, and when it does, rotat1on of the countershaft37. begins. Fig. 28 shows how the cams and gears would stand at thepresent time. 7

Consider a quarter space on the gear .83- as being'the same as a quarterrevolution of the gear 86. Thdfirst quarter revolution (up the mark 1/4)will move the swinging lever 33 into the position in Fig. The carrier2is now swung back into the stack. Now consider the shaft 37 as movingthrough the second quarter and up to the mark 2/4 on the gears. v

Originally the lifting dog 87 (Big. 14) stood in the position marked 0.The first quarter revolution IDOVQd'It up 90 to the i mark 1/4 intoengagement with the nearest tooth 89 of the ack'88. -We a're'nowconsidering the sec nd quarter of revolution of the shaft 37. Rememberthat the carrier 2 is back in the stack. The lifting dog 87 now liftsthe entire stackso as to bring carrier 3 witlrits record into theposition formerly occupied by carrier 2.

Now imagine the'tl'rd quarter of revolution of the shaft 37 astakingplace, occupying the gear 83 up tothe mark 3/4. It s inthis'quarterthat the automatic electric switch 129 is opened by the swtch cam 128. The reader will now understand that had the operator openedthe manual switch 132 in Fig. (or, what is the same thing, pressed oneof the buttons 165 in Figs, 1 and 2,), at any time during the foregoingplaying of the record on carrier 2, the electrical circuit Fig.25) wouldnow be opened at both switc es 129 and 132, and the phonographwould havestopped with the next carrier and a new record in position to be swungout over the turntable upon a subsequent closure ofthe switch 132.

But consider the mark 3/4 as having come into alinement with the idler85. The shaft as taking place, the gear 83 being utilized up to the mark4/4 which is the end of the ar. This last quarter revolution of the saft 37 is occupied in conveyin the cam depression from the position inig. 7, to

that in Fig. 4, by which act carrier 3 is swung back into a osition.over the turntable 13. Compare t a full line position of thecarrierwith the dotted line position of the turntable in Fig. 19. Thisis the relation that the two bear to each other at the present time.

As the end of the gear 83 has been reached, so far as the idler-85 andgear 86 are concerned, the rotation of the countershaft 37 must stop.But the shaft 49 has not coin- .pleted-a full revolution. The cam 48 isapproximately 22 degrees from itsoriginal position in Figs. 6, 11 and27, and accordingly, the shaft 49 has 22 degrees more of angularmovement to make before the cam 48 reaches that position, and before theclutch dog 78 reaches the lateral passage .146.

In this 22 degrees of movement, the cam 48 engages the roller 47, rocksthe raising lever 44, raises the turntable 13 and lifts the new recordoff of the waiting carrier 3. As soon as the dog 78 reaches the passage146, the spring 81 presses the dog out and so the rotation of the shaft49 stops. The upward pressure of the lever 44 in raising the turntablecauses the clutch 80 to start the shaft 14 turning so that thereproduction of the record is begun.

Revert to the time when the pin 73 (Fig. 10) threw the clutch belt 78in. That happened when the stylus 38 reached the end of the record, atwhich time the tone arin 42 was directed toward the observer in Fig. .1.The-lowering of the turntable and record left the reproducer suspendedin a corresponding position and quite out of the way of any adjacentmoving part.

Revert next to the time when the countershaft 37 .made its last quarterrevolution from the position in Fig. 7 to that in 'Fig. 4. .As thecarrier 3 was swung out over the turntable, the flange 40 at one side ofthe carrier engaged the finger .43 (Fig. 19) pendent from thetone armand caused the tone arm to move back to the position in Fig. 1, so thatthe stylus 38 stood over the beginning of the sound. groove on therecord. The subsequent-raising of the turntable and record in the last22 degrees of angular movement of the cam 48 and Shaft 49 brought therecord into engagement with a the stylus 38 for the beginning of theplay- In Tt will be evident to the reader that the axial line of the cam48 (Fig. 6) coincides with the lateral passage 146 (Fig. 12) when thecam reaches its final position in which the turntable stands raised. Itshould also be evident that the clutch dog 78 occupies a positionother-than that in Figs. 5 and. 12 at the time when the 3/4 mark on thegear 83 comes into registration with the idler 85.

This is so because the dog is diametrically opposite to the cam 48, infact bein situated on the axial line thereof, and therefore when thecam/l8 stands in the position in Fig. 26, the dog 78 occupies a positionin the circular opening 147 (Fig. 12)- diametrically opposite. As longas the dog is within the circular opening, a clutch connection betweenthe 'when the phonograph is started again, the

foregoin clutch connection will be maintained t rough the next 112%degrees of angular movement of the shaft 49, this representing the lastquarter of operation of the gear 83 (up to the 4/4 mark) and theaforesaid 22 degrees of movement of the cam 48 to reach the finalposition in Fig. 6.

Repeated periodic revolutions of the shaft 37 and of the lifting dog 87(Fig. 14) will ultimately elevate the rack 88 to such a position whereinthe last carrier 12 and its record .comes into registration with theoutlet openwill lower, the shaft 37 will revolve and the lifting dog 87(Fig. 14) will engage the next to the last rack tooth 89 in Fig. 15after the first quarter revolution of the shaft,v

Upon making the next quarter revolution, the lifting'dog 87 departs fromthe rack.

fhe pin 125 will have released the pawl 121 so that the rack 88 and theentire stack ofcarriers and records is free to gravitate to .the bottom,the 'gravitating motion being retarded'by the dash pot 116 and piston118. The stud 126 behind the rack engages and releases the latch 122 sothat the pawl 121 is freed in time to engage the uppermost tooth 89 ofthe rack 88'and thereby hold carrier 1 in position to be swung out overthe turntable. This is done by the last quarter of the gear 83.
